Answer:

Eye colour is one example of a trait caused by the concentration of melanin in genes.

Explanation:

Eye colour is decided based on two distinct factors- pigmentation of the eye’s iris and scattering of the light by the 'stroma of the iris'. It is a 'polygenic phenotypic' character in a human being.  

The pigmentation of the iris varies between brown and  black, that all depends on melanin concentration in the iris stroma, iris pigment epithelium and the cellular density of trauma. Further, the eye colour genetics are complicated and multiple genes are responsible for same.

hey there!

boiling point is the temperature at which the vapor pressure of the liquid equals atmospheric pressure. the vapor pressure of solvent molecules is decreased when a solute is added, so a higher temperature is required to increase the number of solvent molecules in the gas phase above the liquid.

at the freezing point, the vapor pressures of the solid and liquid are equal; a lower temperature is needed to reduce the number of solvent particles above the liquid.

hope this you
